alright checked that site out and liked the cc503 cam. My question is would this cam pass smog?
Also, regarding a tune. I dont think anyone here local does tuning on the lt1. So would the mail order madz28 or pcmforless work?

You'll need gaskets, rtv, oil, assembly lube, springs, retainers, seats, locks, roller rockers and that's just to start.
Most will also recommend lifters, guideplates, pushrods and a new timing chain as well as an electric wp. HAVE FUN!
If I were you, I'd buy a used shortblock and build that with all new bearings and a forged bottom end. Build it slowly with what money you can and use good quality parts. Be patient and that would work out much better in the end.

alright well...
im not trying to replace the whole motor here, just going for a cam.
I already know im gonna need the basics like oil, gaskets and such.
I plan on gettin .918's and using stock retainers and stock seats.
Also didnt think i would need lifters at all? and would rockers definitely be necessary?
What size are the stock rockers, because the cam i am looking into shows 1.5 rockers is all that is needed.

You're reading it wrong. That's just giving you the lift numbers with 1.5 rockers. The stock rockers are NOT good enough to handle anything more than the stock cam. They are 1.5 ratio, but they are weak. You need to upgrade them whether you get 1.6 ratio or not. Good 1.6 RR are also proven to get about 10hp increase as well. If you're going to do it half-***, just get the LT4 hotcam kit and be happy.

1. Free up about 10hp
2. Allow you to use a double roller timing chain which is better than the LT4ed chain and much cheaper.
It's also proven that it doesn't flow as much water at high RPM either, so that's your decision to make.
